Supreme Court Justice Robert H. Jackson signed this 1948 first
day postal cover honoring the Supreme Court Justice that Jackson replaced on the
court, Justice Harlan Fiske Stone.

Justice Jackson was appointed to the court by President Franklin
D. Roosevelt after serving Roosevelt in various legal roles starting in 1934 and
concluding with the post of Solicitor General. Justice Jackson is widely
credited with being one of the best Supreme Court justices and is widely quoted
today, even in Supreme Court confirmation hearings (Justices Roberts and Alito
being the most recent). My personal favorite is the statement from his dissent
in Terminiello v. City of Chicago, 337 U.S. 1 (1949) that, "There is danger
that, if the court does not temper its doctrinaire logic with a little practical
wisdom, it will convert the constitutional Bill of Rights into a suicide pact."
